Hello, I am running into a strange issue. Trying to export a variable font, I get an incompatibility warning. Inspecting the glyphs in question, I see that the anchor setups are incompatible when I decompose the components:
The decomposition behaves slightly different when the make has a manually set anchor (with the anchor button in the info box). You can remove those manually set anchors.
And the “lam_alefWasla-ar” doesn’t need a “bottom” anchor.
and “behDotless_alefMaksura-ar.fina” misses a “bottom_1” anchor in the Extra Light master.
